First off its an 80's teenish movie

Ok I'm really stumped with this one one, all I remember is that at the start of the film a moody teenager is drinking a can of beer near the edge of this ledge or top of a building ,when he finishes it he puts the can right at the edge. Then he gets on his motorcylce and rides up to it fast, then swerves to kick the can over the edge with the back wheel. The scene ends with him shouting "yes" and punching the air.

He also dyes a rose black to give to his girlfriend later on in the film, and his dad tells him he looks skinny before he goes out to give it to her before some dance or something.

I've seen the actor in a few things, looks vaguely like a cross between stallone, christopher walken and emilio estevez. Think he was blonde.

Any clue or any actors of the period that look kind of like that?

After a breakthrough today (recognizing the actor in the video of 'get into the groove' on TMF I think the film may have been Reckless, 1984 the actor being aidan quinn. Can't be sure about the film only going on synopsis found on Google but that's defo the actor!

You said 80s teen movie if you look up the brat pack you most likely find it a few of the brat pack rob lowe, moly ringwalt, andrew mcarthey, judd nelson, michael anthony hall, cory haim, cory feldman
Sory my spelling is not great
Hope it helps
